corporation of Massachusetts Application July 28, 1932, sci-u No. 625,378 2 Claims." (01. 118-59) This invention relates to the lubrication of vertical flange rings used in machines for twisting yarn. In such machines, the yarn is guided to the rotating spool through a metal traveler mounted to rotate on the vertical flange of the twister ring.

The twisting of heavy yarn develops so much friction between the travelerand the ring that the travelers are quickly burned and destroyed unless the rings are lubricated. Devices for lubricating the rings have. been heretofore provided but have not come into extensive use and the rings are still largely lubricated manually.

An improved lubricating device is shown in the prior application of Aldrich, Serial No. 587,738, filed January 20, 1932. It is the general object of my present invention to further improve the construction shown by Aldrich, and particularly to provide improved means for stor ing lubricant and for supplying the same to the lubricating wicks.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Preferred forms of the invention are shown in the drawing, in which Fig. 1 is a plan view of one form of my invention;

Fig. 2 is a side elevation thereof, partly in section, taken along the line 2--2 in Fig. 1; h Fig. 3 is an enlarged detail plan view of the lubricating device, partly in section;

Figs. 4 and 5 are detail sectional elevations, taken along the lines 4-4 and 5-5 respectively in Fig. 3;

Fig. 6 is a plan view of a modified construction:

Fig. 7' is a side elevation, partly in section,

taken along the lines 7-7 in Fig. 8;

Fig. 8 is an enlarged detail plan view of the form of lubricating device shown in Figs. 6 and 7, and

Fig. 9 is a detail sectional view, taken along the line 99 in Fig. 8.

Referring to Figs. 1 to 5, I have shown'a vertical flange twister ring 10 mounted in a holder 11,

which in turn is secured by screws 12 to the usual ring rail 13. A traveler T of the usual form is mounted to slide rotatably on the ring 10.

The ring 10 is also preferably provided with a short segmental horizontal slot or recess 15 (Fig. 3) in its inner face and with radial openings 16 connecting thereto. A wick W is disposed in the slot 15 and openings '16, this portion of the wick being preferably continuous, and the two end.

portions of the wick are disposed in a recess 20 formed in an outwardly projecting ear 21 of the holder 11. Slots 22 in the upper edge of the holder. 11 connect the recess 20 and the radial openings 16.

Discs or pads 23 are mounted in the recess 20, preferably above and below the ends of the wick W, and preferably substantially filling the circular recess 20.

The holder 11 is also provided with a. small supplementary recess 25, which is in free communication with the recess 20 but which does not contain any portion of the pads 23 or wick W. It will be noted that the bottom of therecesses 20 and ;25 issubstantially lower than the segmental slct 15.

In the use of the invention, the supplementary recess 25 is filled with oil or other suitable lubricant, which is absorbed by the pads 23 and is by. them transferred to the wick W, which gradually conveys the lubricant by capillary action to the inside of the ring 10 where the wick may be brushed by the traveler and also supplies lubricant to the innerface of the ring. With this construction it is found that a satisfactory flow of oil to the inner face of the ring 10 will take place. h

In Figs. 6 to 9 I have shown a slightly modified construction of my invention. In these fig-v ures, a vertical traveler ring 30 is supported in a sheet metal ring holder 31 and is provided with the usual traveler T.

An elongated cup-like member 32 is secured to the outer face of the ring holder 31 and provides an elongated recess 33 to receive pads 34, substantially as in the construction previously described.

I use the same wick W with the same radial openings 16 and the same horizontal segmental slot 15. Slots 35 (Fig. 8 and 9) communicate with the radial openings 16 as previously described.

Preferably the pads 34 are cut away at one corner, as indicated at 40 in Fig. 6,. thereby providing a supplementary oil recess corresponding in function to the recess 25 in the first described form. If the cut away portion or recess 40 is filled with a suitable lubricant, the ring 10 is venting excessive wear thereof.

Having thus described my invention and the advantages thereof, I do not wish to be limitedto the details herein disclosed, otherwise than as set forth in' the claims; but what I claim is:

1. In a twister, in combination, a. vertical flange ring having radial openings therethrough, a wick disposed in said openings, a ring holder having a recess substantially circular in cross section and having a smaller offset circular oil storage recess in-iree communication with said first recess, and circular pads of absorbent material filling said first recess and positioned above and below the ends of said wick.
